Introduction:
Modelling Relationships and Controlling Events

During this case study, you will discuss and develop your skills in using ICT in teaching and learning to do the following:

• Use ICT to model relationships - this is specific to this case study.

Plus you will develop your ability to:

• Plan for the effective use of ICT.
• Organise classroom use of ICT.
• Prepare and present materials for learners using ICT.
• Use the functions of ICT and understand its limitations.
• Review and evaluate courseware and software.
• Relate the use of ICT to learners needs.
• Develop your learners' subject based learning using ICT.
• Assess your learners' progress in Application of Number as a result of using ICT.
• Help develop your learners' capability in the use of ICT.
• Help your learners develop within the IT curriculum.

The first of these objectives is specific to this case study, and represents the core of what the case study is about. Although you should find similarity with the first case study since the student is expected to manipulate functions in the spreadsheet. The other objectives are common to all three of the case studies in Application of Number, and represent the application of your understanding of ICT to teaching and learning.

Before we go into detail in the case study, we should look more closely at what is meant by modelling relationships:

• Exploring mathematical relationships between numeric variables.
• Representing simple relationships involving basic arithmetic operations as algebraic formulas.
